Dr. Eugene is a very very careful and meticulous doctor. I know for a fact he has treated countless countless patients with difficult problems successfully and they are all well and disease free when other doctors couldn't do anything and told them its not curable even from big big Hospitals. I can only say generally. Some patients have simple problems which require simple cures. Some have medium problems that require medium cures. Some have complex complex rare issues that require complex complex complex cures or attempts to cure. Illnesses can range from very very very simple to average complex to super complex. Some respond. Some due to complexity of problems have complex responses to treatment that can come from many many irreconcilable factors. Meddling with unverified supplements by own patient may not help. What Nature gives to some is unkind but it is all in God's hands. What Nature doesn't give to some is also in Gods hands. I know a friend who had brain tumour at age 30. I know a friend who had leukemia at age 2. I know a friend who had bone cancer at age 25. I know a friend who had testicular tumour at age 19. I know a friend who had heart attack at age 35. I know a friend who had ovarian cancer at age 39. Rare rare conditions are all in Gods hands. Many of Dr Eugene's patients with illness are alive and well and are actively active and well. Some of these patients are now in their 60s, 70s, 80s and some almost 90, cured. God Bless.
